Is there any danger to updating a new Kobo Clara to latest firmware when prompted?

I have just gotten a new Clara HD, and the sync is prompting me to update the firmware to the latest version.

I'm tempted because I'd like to see what the latest version feels like.

But I'm also worried that I'll lock myself out of any mod, etc. because I won't be able to downgrade or root it.

So, should I update to the latest version when prompted with sync or is it a bad idea for future tinkering?
